| titleOfInvention | Optical film manufacturing method and optical film |
| abstract | In a sequential biaxial stretching in which a thermoplastic resin film is stretched longitudinally and then transversely stretched, an optical film production method capable of producing an optical film having good optical characteristics with less bowing and reduced thickness unevenness, and the An optical film produced by the method is provided. In the method for producing an optical film having a longitudinal stretching step of stretching a long thermoplastic resin film in the longitudinal direction and then a transverse stretching step of stretching in the width direction, the thermoplastic resin film is longitudinally stretched in the longitudinal stretching step. When stretching, the temperature of both end portions of the thermoplastic resin film is higher than the temperature of the central portion. |
